I think they’re this powerful right now because there are a lot of non-billionaires who are dumb enough to do whatever they’re told by them even if it’s not in their own best interest (or the rest of the world’s) at all.
And they always will be. The thing about one’s own best interest is that it’s self-interest, always at least parochial, if not outright selfish (as in the US). If the people comprising a billionaire’s private security force can obtain a better standard of living, more power, more perks, for themselves and their families than they could by cooperating with the rest of the proles in a (let’s be honest) speculative venture, even if it did pay off? Well, some people will take the billionaire’s offer, at least enough people to comprise a private security force.
